Optimal cutting qualitySolid base structure which ensures perfect stability, maximum quality and long term reliability of machining operations.

The blade deflections device controls the position and the number of revolu-tions of the blade, intervening to adjust the advance speed. Maximum cutting quality, a longer blade lifespan, and re-duced maintenance costs.

The optimal balancing and weight distri-bution on the two guides guarantees the total absence of vibrations and perfectly straight cutting action.

The motorised vertical movement of the blade ensures fast, precise blade projection adjustment. The fixed motor of the main blade is not raised during the cut, and ensures the perfect balancing of the blade carriage.

7

Air-cushioned working surface to handle delicate materials. In addition, this char-acteristic ensures the surface next to the blade is kept constantly clean.

Cut line closure system, to prevent rip trim cuts from falling into the machine and fouling the blade path.

Front and rear rip trims are disposed of by means of a dedicated and fully au-tomated dump table with independent rollers.

Top-quality finished product

The double pressure beam has independent structure, enables the application of con-sistent, controlled pressure on the stack of panels to be cut. The absence of openings for the grippers creates a real airtight chamber for trim cuts, with an efficient vacuum for the removal of dust.

8

The sturdy pushing carriage positions the panels quickly and accurately, thanks to its brushless motor. The slide surface below the pushing device is fitted with independent rollers to avoid marking delicate surfaced panels.

Powerful front aligners align the book of panels against the pushing points.

The slide surface is fitted with independ­ent idle rollers to avoid any frictions on panels surfaces.

Machining operation precision

9

Thin panels can be loaded from the lifting table, using independent floating pushing points that are electronically controlled. A specific logic together with the front pop-up stops prevent the risk of misfeeding (by means of attrition) those panels that don't belong to the book being fed.

Side alignment stop integrated in the cross cut blade carriage. Its features enable the perfect alignment of even the thinnest and/or most flexible pan-els, reducing cycle time to a minimum.

A solution to any requirement

10

Quick set-up timesPatented systems for quick and easy adjustments.

Fast, accurate setting of the scoring and main blades, using the Digiset sys-tem both vertical and horizontal.

The “Quick change” system is the quickest, most ergonomic and safest device for changing blades without us-ing tools.

11

Thanks to the system for the automat-ed change of the main blade and the relevant software, the blade can be changed in a fully automated manner in just a few seconds, ensuring precise adjustment and reducing cycle times at the same time.

Automatic alignment. The patented system automatically aligns the scor-ing blade in seconds, which complete-ly eliminates test cuts, reduces set-up time which increases efficiency and reduces production costs.

1212

Simultaneous multiple actionSystem for performing simultaneous transverse cuts due to the two fully independent pushing devices and two completely independent motor-less grippers. This mechanism changes distance between the two pushing devices and therefore their working field.This enables the processing of panels up to 5.7M x 2.7M.

1313

Significant reduction of machining times, thanks to the possibility to combine the grippers with any type of cutting pattern and execute it in a single cycle. A perfect combination of Biesse optimisation and Italian genius.

14

Depending on the cutting pattern, the two idle grippers can link up (either indi-vidually or together) with the two push-ing devices.

A wide range of configuration possibilities to process efficiently a variety of cutting patterns.

Maximum productivity on any pattern

1515

Differentiated cross-cut, also for narrow strips.

The two cutting stations can execute cut-ting patterns completely independently, thanks to the presence of an intermedi-ate zone that can accommodate a whole panel. Both areas are fully covered in in-dependent rollers to preserve the panel’s surface.

16

Infeed conveyors with free-running or powered rollers allow the side and/or rear loading/unloading of panel stacks.

Double-level infeed conveyor. Thanks to the reduced footprint, which utilises height, the double-level infeed conveyor enables the optimisation of space and is perfectly suited to production sites that cannot accommodate two conveyors side by side.

The lift table consists of a strong frame which is equipped with a special struc-ture to load the pack of panels directly by forklift.

Special solutions for handling stacks and feeding and unloading panels available upon request.

Reduced panel loading and partial bunk unloading

1717

Front aligners to align the boards in the width directly on the turn station unit.

The (patented) rotating station rotates the stack of panels, maintaining the alignment with the point of reference both before and after rotation. Panel clamping devices avoid the misalign-ment of the stack during the rotation phase.

Wide range of configuration options to facilitate panel unloading.

Loading and uploading optimised for large volumes.

Easy cutting pattern programming.

An effective diagnosis and troubleshooting program provides complete information (photos and text) to en-sure that any problems are quickly resolved.

Advance statistics management which allows the pro-cessing of machine productivity and operation data.

Graphic simulation in real time, with messages and in-formation for the operator.

The numerical control guarantees the fully automated management and execution of cutting patterns, and optimises all movements relative to controlled axes (i.e. pusher and saw carriage, pressure beam, blade height). It ensures the blade protrudes from the book to the correct height during sectioning, and calculates the most suitable cutting speed on the basis of the book height and trim cut width. It helps ensure the best cutting quality at all times.

A-weighted surface sound pressure level (LpfA) during machining on the operator workstation on a machine with vane pumps Lpa=82dB(A) Lwa=107dB(A). A-weighted sound pressure level (LpA) on the operator workstation and sound pow-er level (LwA) during machining on a machine with cam pumps Lwa=82dB(A) Lwa=107dB(A). Meas-urement uncertainty K dB(A) 2.

The measurement was carried out in compliance with UNI EN 848-3:2007, UNI EN ISO 3746: 2009 (sound power) and UNI EN ISO 11202: 2009 (sound pressure levels at workstation) during panel machining. The noise levels shown are emission levels and do not necessarily correspond to safe operation levels. Despite the fact that there is a relationship between emission and exposure levels, this may not be used in a reliable manner to establish whether further measures need to be taken. The factors determining the exposure level for the workforce include length of exposure, work environment characteristics, other sources of dust and noise, etc. i.e. the number of other adjoining machines and processes. At any rate, the above information will enable the operator to better evaluate dangers and risks.

Biesse technology accompanies the growth of Stechert

“On these chairs sits the world" is the motto of the Stechert Group that can effectively be taken literally. What began 60 years ago as a small manufacturing company for pram mouldings, furniture doors and door locks is today one of the largest international suppliers of con-tract and office chairs, as well as tubular steel furniture. Moreover, since 2011 the company has a partnership with WRK GmbH, an international specialist in podiums, conference room and grand-stand seating, associated with Stechert via the joint commercial company STW. For Stechert management, howev-er, the excellent results obtained are no excuse for resting on their laurels. On the contrary, the company is invest-ing heavily in the Trautskirchen site to make its production even more efficient and profitable. In the search for a new machinery partner, the company's man-agement chose the Italian manufacturer Biesse. “For the project we chose ma-chines that already had certain options and were predisposed for automation", said Roland Palm, Biesse Area Manager.

An efficient production cycle was creat-ed in which workers are able to perform at their best after only a short training period.At the start of the production line is the beam saw “WNT 710” with one cutting line. “Because”, explained skilled cab-inet maker Martin Rauscher, “we want to be able to work panels of up to 5.90 metres in order to reduce waste as much as possible.” Normal rectangular panels for tables or wall panels are tak-en directly to the “Stream” edgebander with “AirForceSystem” technology. The Biesse edgebander has a group that activates the laminated edging materi-al no longer via a laser beam but using hot air to obtain the so-called “zero gap”. “The quality is just as good as the laser system, if not even better: with a con-nection power of 7.5 kW, the cost per square metre is much lower", underlined the Biesse Area Manager.“We want to be ready for when we mould the frame ourselves and we must there-fore calibrate the panels” said Martin Rauscher, “The same is true of course

for solid wood and multiplex panels, which require grinding before being painted in an external company. For both types of work a Biesse “S1” sand-er is used. In order to meet the needs of the future, in the Trautskirchen plant there are also two Biesse numerically controlled machining centres: a “Rover C 965 Edge” and a “Rover A 1332 R”, which are perfectly complementary. The Stechert Group also intends to strengthen sales of innovative solu-tions for interior fittings, with complete systems for walls, ceilings, floors and mezzanines. For panel sectioning, the Group has purchased a "Sektor 470". For other geometry, groove and spring machining as well as boring and surface milling, there are two Biesse machining centres, an “Arrow” for nesting applica-tions, a “Rover B 440” and more recently a 5-axis machine, the “Rover C 940 R” machining centre in order to be able to produce, in particular, wall and ceiling panels machined in 3 dimensions.
